How and Why to Insulate your Loft in Hanworth

Loft conversions in Hanworth are best for increasing living space in your home, and having it adequately insulated is one way to ensure that your new loft conversion is as comfortable and enjoyable as possible. Furthermore, proper insulation in your loft conversion in Hanworth may result in an upgraded EPC rating for your property, increasing the value of your home. However, loft conversions in Hanworth take time and money and should be carefully considered before proceeding with any plans, including insulation.


Building codes have become more stringent in recent years, which means that roof rooms converted more than ten years ago are unlikely to meet current standards. Standards were relatively low prior to 2003, so if your loft was converted a long time ago, there may be very little insulation. Currently, loft conversion building codes require that the roof's U-value be 0.18W/m2 or less. This equates to a layer of fiber/wood insulation 270mm thick, 175mm of board insulation, or 125mm of high-performance spray foam. If you're having your loft converted right now, the insulation should meet the aforementioned standards and thickness. During the re-roofing process, insulation can be added externally between the new roof and the roof room ceiling.


It is recommended that you insulate the roof both between and under the rafters if you share a roof with a neighbor or if the roof covering is not being replaced. This frequently entails installing a layer of insulation between the rafters and a second layer beneath the rafters to help reduce thermal bridging. Because the rafters are not part of the insulated structure, this construction method is known as a "cold roof." When installing insulation between rafters and sarking felt, leave a 50mm gap above the insulation for ventilation. Furthermore, the insulation must be level with the bottom of the rafters. Under this, the insulated plasterboard should be installed.


It is strongly advised that insulation be installed both between and above the rafters when re-roofing a detached property, also known as a 'warm roof,' because the majority of the insulation is placed above the roof's timbers. Roofing timbers are well insulated, which means they provide a significant amount of warmth. This has the advantage of providing more headroom within the converted loft, which is extremely convenient. This method, however, is only appropriate when all of the roofing has been removed, allowing builders access to the rafters themselves.


In general, insulating a standard loft is relatively simple, but retrofitting insulation can be extremely expensive, so it may not be a viable option for some who want to insulate their loft. To keep your house up to code, you will need to insulate the three different areas of your loft conversion in Hanworth.

A Loft Conversion is the quickest way of increasing the amount of living space in your Hanworth home. Did you know recent research undertaken by Nationwide Building Society has shown that a Loft Conversion can add over 20% to the value of your property? Moreover, it can improve your home’s energy efficiency too. All that extra insulation will surely bring down the cost of your energy bills. By converting your loft, it makes use of “unused” space to create an extra bedroom or bathroom, rather than eating into your garden. Overall, it costs less per square metre to convert a loft rather than build a rear or side extension, as most of the structure needed is already in place. Most of the loft conversions can be carried out without the need for planning permission if they don’t exceed a certain size. (40 cubic metres for a terraced property and 50 cubic metres for a detached house).


To select the right type of Loft conversion for your home, you will need to consider the shape, height, and line of your existing roof. Your budget and planning permission rights also need to be considered. There are five main types of Loft Conversion: Roof Light/Velux Conversions, Dormer Conversions, Hip-to-gable Conversions, Mansard Conversions and L-shaped conversions. Internal Loft Conversions are usually the cheapest and require least building intervention. Dormer Conversions are the most common type because of the space they add. Mansard gives you the utmost flexibility but is the most complex and expensive to build. If you’re considering a Loft Conversion but can’t quite understand where to begin, our experienced team can answer all your questions.


The average cost of a Loft Conversion in Hanworth is between £40,000 to £90,000.

A loft conversion will not only give you extra space but also enhance your living space on your property. A loft conversion price depends on many factors such as type of the conversion, type of the roof you have, type of the lighting you want in the loft, the type of windows required, the size of the project, fixtures and fittings, nature of the exterior, client's personal requirements and the site's location.
